  • In this study, antioxidative effects and inhibitory effects of Geum aleppicum Jacq. extracts on tyrosinase and elastase were investigated. The ethyl acetate fraction of G. aleppicum Jacq. extract ($4.70\;{\mu}g$/mL) showed the most prominent free radical (1,1-diphenyl-2-picrylhydrazyl, DPPH) scavenging activity (FSC50). Reactive oxygen species (ROS) scavenging activities ($OSC_{50}$) of some G. aleppicum Jacq. extracts on ROS generated in $Fe^{3+}-EDTA/H_2O_2$ system were investigated using the luminol-dependent chemiluminescence assay. The ethyl acetate fraction showed the most prominent ROS scavenging activity ($0.22 \;{\mu}g$/mL). The protective effects of extract/fraction of G. aleppicum Jacq. against the rose-bengal sensitized photohemolysis of human erythrocytes were investigated. The G. aleppicum Jacq. extracts suppressed photohemolysis in a concentration dependent manner ($1{\sim}25{\mu}g$/mL), particularly the ethyl acetate fraction exhibited the most prominent celluar protective effect (${\tau}_{50}$, 416.20 min at $10 \;{\mu}g$/mL). The inhibitory effect of G. aleppicum Jacq. extracts on tyrosinase and elastase were investigated to assess their whitening and anti-winkle efficacy. The half maximal inhibitory concentration ($IC_{50}$) of the ethyl acetate fraction on tyrosinase was $95.23\;{\mu}g$/mL. The $IC_{50}$ of 50 % ethanol extract and the ethyl acetate fraction on elastase were $6.27 \;{\mu}g$/mL and $4.31 \;{\mu}g$/mL, respectively. These results indicate that extract/fraction of G. aleppicum Jacq. can function as antioxidants in biological systems, particularly skin exposed to UV radiation by scavenging $^1O_2$ and other ROS, and protect cellular membranes against ROS. Especially the ethyl acetate fraction of G. aleppicum Jacq. extracts could be applicable to new functional cosmetics for antioxidant, antiaging.

  • In this study, the antioxidative activity, inhibitory effects on tyrosinase and elastase, and active components of Quercus salicina Blume extracts were investigated. Q. salicina Blume was extracted using 50 % ethanol, from which ethyl acetate and aglycone fractions were prepared. The DPPH (1,1-diphenyl-2-picrylhydrazyl) scavenging activity ($FSC_{50}$) of Q. salicina Blume aglycone fraction was the highest ($8.25\;{\mu}g$/mL). The luminol-dependent chemiluminescence assay showed that reactive oxygen species (ROS) scavenging activities ($OSC_{50}$) of Q. salicina Blume aglycone fraction on ROS generated in $Fe^{3+}-EDTA/H_2O_2$ system was the most prominent at $0.039\;{\mu}g$/mL. The protective effects of extract/fractions of Q. salicina Blume against the rose-bengal sensitized photohemolysis of human erythrocytes were increased in a concentration dependent manner ($1{\sim} 25\;{\mu}g$/mL). Especially, ${\tau}_{50}$ of aglycone fraction in $10 \;{\mu}g$/mL concentration showed the most protective effect at 259.9 min. The inhibitory effects ($IC_{50}$) on tyrosinase and elastase of Q. salicina Blume extracts were higher at aglycone fraction (respectively, $21.82 \;{\mu}g$/mL, $41.18\;{\mu}g$/mL). Active component analysis by TLC and HPLC showed quercetin, keampferol, catechin, quercitrin, isoquercitrin, hyperoside, and etc. These results indicate that Q. salicina Blume extract has strong antioxidative activity and can be used as antioxidant. Particularly, aglycone fraction of Q. salicina Blume showed superior antioxdative activity and high inhibitory effect on tyrosinase and elastase. Therefore, aglycone fraction of Q. salicina Blume could be applicable to new functional cosmetics.

Aglycone fractions obtained from the deglycosylation reaction of ethyl-acetate fraction among the Geranium nepalense extracts, showed 2 bands in TLC and 2 peaks in HPLC experiments (370 nm). Two components were identified as quercetin(composition ratio, 15.3%), kaempferol(82.8%). These results indicate that extract/fractions of Geranium nepalense can function as antioxidants in biological systems, particularly skin exposed to UV radiation by scavenging $^1O_2$ and other ROS, and protect cellular membranes against ROS. And component analysis of Geranium nepalense extract and inhibitory activity on elastase of the aglycone fraction could be applicable to new functional cosmetics for smoothing wrinkles.

  • In this study, the antibacterial, antioxidative and inhibitory effects of Allium cepa peel extracts on tyrosinase and elastase were investigated. MIC values of the ethyl acetate fraction of Allium cepa peel on especially, S. aureus among the skin resident flora (Staphylococcus aureus, S. aureus; Propionibacterium acnes, P. acnes; Pityrosporum ovale, P. ovale; Escherichia coli, E. coli) were 0.06%. The aglycone fraction showed more excellent free radical (1,1-diphenyl-2-picrylhydrazyl radical, DPPH) scavenging activity ($FSC_{50}=5.05{\mu}g/mL$). Reactive oxygen species (ROS) scavenging activities ($OSC_{50}$) of the ethyl acetate fraction and aglycone fraction in the luminol-dependent $Fe^{3+}-EDTA/H_2O_2$ system were 0.05 and $0.03{\mu}g/mL$, respectively. The cellular protective effect of the aglycone fraction on the rose-bengal sensitized photohemolysis of human erythrocytes exhibited more prominent (${\tau}_{50}$, 480 min at $25{\mu}g/mL$). The inhibitory effects ($IC_{50}$) of the ethyl acetate fraction and aglycone fraction on tyrosinase were 9.16 and $8.68{\mu}g/mL$, the inhibitory effect ($IC_{50}$) of the aglycone fraction on elastase was $14.12{\mu}g/mL$ The transepidermal water loss of the cream containing 0.1% ethyl acetate fraction was decreased from $8.3g/m^2h$ in control to $6.8g/m^2h$ in the subjects applied with cream containing the ethyl acetate fraction. These results indicate that extract/fractions of Allium cepa peel can function as antioxidant in biological systems, particularly skin exposed to UV radiation by scavenging $^1O_2$ and other ROS, and protect cellular membranes against ROS, and possibly as antiaging agents. Allium cepa peel extract could be used as a new cosmeceutical for whitening and anti-wrinkle products.

  • Objective: To observe the effects of allogeneic and autologous transfusion on cellular immunity, humoral immunity and secretion of serum inflammatory factors and perforin during the perioperative period in patients with malignant tumors. Methods: A total of 80 patients (age: 38-69 years; body weight: 40-78 kg; ASA I - II) receiving radical operation for gastro-intestinal cancer under general anesthesia were selected. All the patients were divided into four groups based on the methods of infusion and blood transfusion: blank control group (Group C), allogeneic transfusion group (group A), hemodiluted autotransfusion Group (Group H) and hemodiluted autotransfusion + allogenic transfusion Group (A+H group). Venous blood was collected when entering into the surgery room ($T_0$), immediately after surgery ($T_1$) and 24h ($T_2$), 3d ($T_3$) and 7d ($T_4$) after surgery, respectively. Moreover, flow cytometry was applied to assess changes of peripheral blood T cell subpopulations and NK cells. Enzyme linked immunosorbent assays were performed to determine levels of IL-2, IL-10, TNF-${\alpha}$ and perforin. Immune turbidimetry was employed to determine the changes in serum immunoglobulin. Results: Both CD3+ and NK cells showed a decrease at $T_1$ and $T_2$ in each group, among which, in group A, CD3+ decreased significantly at $T_2$ (P<0.05) compared with other groups, and CD3+ and NK cell reduced obviously only in group A at $T_3$ and $T_4$ (P<0.05). CD4+ cells and the ratio of D4+/CD8+ were decreased in groups A, C and A+H at $T_1$ and $T_2$ (P<0.05). No significant intra- and inter-group differences were observed in CD8+ of the four groups (P<0.05). IL-2 declined in group C at $T_1$ and $T_2$ (P<0.05) and showed a decrease in group A at each time point (P<0.05). Moreover, IL-2 decreased in group A + H only at $T_1$. No significant difference was found in each group at $T_1$ (P<0.05). More significant decrease in group ?? at $T_2$, $T_3$ and $T_4$ compared with group A (P<0.05), and there were no significant differences among other groups (P>0.05). IL-10 increased at $T_1$ and $T_2$ in each group (P<0.05), in which it had an obvious increase in group A, and increase of IL-10 occurred only in group A at $T_3$ and $T_4$ (P<0.05). TNF-${\alpha}$ level rose at $T_1$ (P<0.05), no inter- and intra-group difference was found in perforin in all groups (P<0.05). Compared with the preoperation, both IgG and IgA level decreased at $T_1$ in each group (P<0.05), and they declined only in Group A at $T_2$ and $T_3$ (P<0.05), and these parameters were back to the preoperative levels in other groups. No significant differences were observed between preoperative and postoperative IgG and IgA levels in each group at $T_4$ (P>0.05). No obvious inter- and intra-group changes were found in IgM in the four groups (P>0.05). Conclusions: Allogeneic transfusion during the perioperative period could obviously decrease the number of T cell subpopulations and NK cells and the secretion of stimulating cytokines and increase the secretion of inhibiting cytokines in patients with malignant tumors, thus causing a Th1/Th2 imbalance and transient decreasing in the content of plasma immune globulin. Autologous transfusion has little impact and may even bring about some improvement oo postoperative immune function in patients with tumors. Therefore, cancer patients should receive active autologous transfusion during the perioperative period in place of allogeneic transfusion.

  • In this study, the cellular protective effect, antioxidative property and component analysis of Euphorbia humifusa extracts were investigated. The ethyl acetate fraction ($3.68\;{\mu}g/mL$) and aglycone fraction ($3.15\;{\mu}g/mL$) of Euphorbia humifusa extract showed prominent free radical (1,1-diphenyl-2-picrylhydrazyl, DPPH) scavenging activity ($FSC_{50}$). Reactive oxygen species (ROS) scavenging activity ($OSC_{50}$) of Euphorbia humifusa extract on ROS generated in $Fe^{3+}$-EDTA/$H_2O_2$ system was investigated using the luminol-dependent chemiluminescence assay. The ethyl acetate fraction ($0.43\;{\mu}g/mL$) and aglycone fraction ($0.35\;{\mu}g/mL$) of extract showed higher ROS scavenging activity than L-ascorbic acid ($1.50\;{\mu}g/mL$). The cellular protective effects of fractions of Euphorbia humifusa extract on the rose-bengal sensitized photohemolysis of human erythrocytes were investigated. The ethyl acetate fraction and aglycone fraction of extract protected cellular membranes against ROS in a concentration dependent manner ($5{\sim}25\;{\mu}g/mL$), and was more effective than (+)-${\alpha}$-tocopherol, lipid peroxidation chain blocker. Aglycone fraction from Euphorbia humifusa extract showed 2 bands in TLC and 2 peaks in HPLC. In HPLC chromatogram of aglycone fraction, peak 1 and peak 2 were identified as quercetin and kaempferol, respectively. And these components are very effective as antioxidant. Thus, these results indicate that fractions of Euphorbia humifusa extracts can function as antioxidant in biological systems, particularly skin exposed to UV radiation by scavenging $^1O_2$ and other ROS, and protect cellular membranes against ROS. Fractions of Euphorbia humifusa extracts can be applicable to new functional cosmetics for antioxidant.

  • In this study, the antioxidative effects and inhibitory effects on tyrosinase and elastase of Sorbus commixta (S. commixta) twig extracts were investigated. The aglycone fraction of S. commixta twig extract showed the prominent free radical (1,1-diphenyl-2-picrylhydrazyl, DPPH) scavenging activity($FSC_{50}$, $13{\mu}g/mL$). Reactive oxygen species (ROS) scavenging activities of S. commixta twig extracts on ROS generated in $Fe^{3+}-EDTA/H_2O_2$ system were investigated by the luminol-dependent chemiluminescence assay. The 50 % ethanol extract among extracts showed the most prominent ROS scavenging activity ($OSC_{50}$, $0.189{\mu}g/mL$). The cellular protective effects of extract/fractions of S. commixta twig on the rose-bengal sensitized photohemolysis of human erythrocytes were investigated. The 50 % ethanol extract and ethyl acetate fraction showed the cellular protective effects against ROS in a concentration dependent manner ($5{\sim}50{\mu}g/mL$). The inhibitory effect of S. commixta twig extract on tyrosinase was investigated to assess the whitening efficacy. The ethyl acetate ($IC_{50}$, $113.2{\mu}g/mL$) and aglycone fraction($IC_{50}$, $105.3{\mu}g/mL$) on tyrosinase showed more remarkable inhibitory effect than arbutin($IC_{50}$, $226.88{\mu}g/mL$), known as the whitening agent. The inhibitory effect of aglycone fraction ($IC_{50}$, $6.9{\mu}g/mL$) on elastase was simillar to quercetin($IC_{50}$, $6.1{\mu}g/mL$), flavonoid known as reference compound. These results indicate that extract/fractions of S. commixta twig can function as antioxidants in biological systems, particularly skin exposed to UV radiation by scavenging $^1O_2$ and other ROS, and protect cellular membranes against ROS. S. commixta twig extracts can be applicable to new functional cosmetics for anti-aging products.

  • This study was carried out to investigate the antioxidative activities of Rosa davurica Pall for the purpose of development of novel antioxidant from natural products. Antioxidant activities of four different parts of Rosa davurica Pall such as fruit, leaf, stem and root were examined by measuring the radical scavenging effect on 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical. The methanol extract from the root of Rosa davurica Pall showed the highest antioxidative activity among 16 samples tested. And, we also tested radical scavenging effects of 5 different extract compartments(Hexane, $CHCl_3$, EtOAc, BuOH and $H_2O$ fraction). EtOAc and BuOH fractions from the root of Rosa davurica Pall exhibited antioxidative activities higher to those of natural, ${\alpha}-tocopherol$ or synthetic antioxidants, BHT. The antioxidative substance of EtOAc fraction from the root of Rosa davurica Pall was successively purified with silica gel adsorption column chromatography and Sephadex LH-20 column chromatography. The purified active substance was isolated as crystal and identified as (+)-catechin by $^{l}H-NMR$ and $^{13}C-NMR$. This compound exhibited DPPH radical scavenging activity with the $IC_50$ value of $1.7\;{\mu}g/ml$. In the analysis of catechin content, the leaf extracts contained the highest catechin, and fruit extracts contained the lowest catechin. Considering antioxidative activity on DPPH assay, the extracts of Rosa davurica Pall showed a possibility to be used as a new material for natural antioxidant and functional food.

  • For those unfamiliar with the shoe world, Pinet (1817-1897) was a contemporary of Worth, the great Parisian couturier. So I look at the glamour shoes and the world of haute couture, and indeed the development of the named designer. That is a concept we are all familiar with now. So it is not easy to comprehend the lack of names for the exquisite work before 1850. Straightway I have to say that the number of noted shoe designers is far fewer than famous dress designers, but I will introduce you to some of them, against the background of contemporary shoe fashions. Franc;ois Pinet was born in the provinces (probably Touraine) in 1817, two years after the end of the Napoleonic Wars. His father, an ex-soldier, settled to shoemaking, a comparatively clean and quiet trade. It had a tradition of literacy, interest in politics, and was known as the gentle craft, which attracted intelligent people. We should presume father would be helped by the family. It was usual for a child to begin by the age of 5-6, tying knots, sweeping up, running errands and gradually learning the job. His mother died 1827, and father 1830 when he was 13, and at the time when exports of French shoes were flooding world markets. He went to live with a master shoemaker, was not well treated, and three years later set out on the tour-de- France. He worked with masters in Tours and Nantes, where he was received as Compagnon Cordonnier Bottier du Devoir as Tourangeau-Ia rose dAmour (a name to prove most appropriate). He went on to Bordeaux, where at 19 he became president of the local branch. In 1841 he went to Paris, and in 1848, revolution year, as delegate for his corporation, he managed to persuade them not to go on strike. By now the shoemakers either ran or worked for huge warehouses, and boots had replaced shoes as the main fashion. In 1855 Pinet at the age of 38 set up his own factory, as the first machines (for sewing just the uppers) were appearing. In 1863 he moved to new ateliers and shop at Rue ParadisPoissoniere 44, employing 120 people on the premises and 700 outworkers. The English Womans Domestic Magazine in 1867 records changes in the boots: the soles are now wider, so that it is no longer necessary to walk on the uppers. There is interest in eastern Europe, the Polonaise boots with rosette of cord and tassels and Bottines Hongroises withtwo rows of buttons, much ornamented. It comments on short dresses, and recommends that the chaussure should correspond to the rest of the toilet. This could already be seen in Pinets boots: tassels and superb flower embroidery on the higher bootleg, which he showed in the Paris Exposition that year. I think his more slender and elegant Pinet heel was also patented then or 1868. I found little evidence for colour-matching: an English fashion plate of 1860 shows emerald green boots with a violetcoloured dress.
